This invention relates to win-ding machines and particularly to machines in which the winding spindle is driven at a constant rate of speed and the strand of yarn or the like delivering thereto` is taken up by the winding package at a progressively increasing linear rate of draft.

In the present specification and claims the term yarn is used broadly to indicate any form of strand material such as silk, rayon, cotton or the like, and the term package -is employed in a generic sense to indicatethe product of the machine Whatever its character.

One object of the invention is to provide in a machine of the present type means for maintaining a substantially uniform or in some instances a gradually decreasing tension on the winding strand as its linear speed increases and means for applying a uniform amount of liquid, such as an emulsionof oil or the like, to the yarn during its linear travel to the winding package at a constantly increasing speed.

Another object of the invention is to provide in a machine of the type specified means actuated during the growth in diameter of the package being wound to control the tension applied to the feeding strand of yarn, and also the amount of liquid supplied for moistening or emulsifying the yarn in accordance with the changing speed of draft of the latter.

Another object of the invention is to provide in a machine of the present type means for contacting the yarn with a wetted surface across which it feeds and means for varying the extent' of the contact in proportion to the increasing speed of the yarn as it is wound into the package whereby to moisten the `material uniformly throughout the Whole winding operation.

Another object of the invention is to provide a machine of the type indicated which is eillcient and positive in performing its intended functions and adapted for use over long periods of time without requiring adjustment, repair or replacement of its parts.

Further objects of the invention are set forth in the following speciilcation which describes a preferred form of construction of the improved winding machine and several modied forms of the controlling means therefor as illustrated by the accompanying drawings. In the drawings:

Likewise, cotton yarns are sometimes moistenedor treated by a suitable liquid during the in general the machine is of a standard type for producing cross-wound packages with a V-wind.

The present drawings illustrate one unit of a gang machine comprising a plurality of spindles. all of substantially the same design and construction.' 'nsshownf'm Fig. 1. each winding' unit or f ing spindle 6 which may be driven from any suitable source of power by means not herein shown. The winding unit may also comprise a reciprocating yam-or thread-guide I Il slidably mounted on a traverse-frame .II which'is pivoted onanshaft j, I2 journaled Iin bearings below and'parallel to it to be acted upon by a cam 35 which is siidable vertically to force the spindle toward the right.- as viewed in Figs. 1 and 9, to relieve the pressure of the springs 23 against the tension-disks 2D. Thecam 35 is in the form of a block or plate carried at the lower end oi a slide-bar 3 6 adapted to be moved vertically from the swinging movement of the traverse-frame II through i connections as next described.

thewinding spindle 6. A suitable cam 1 enclosed within the frameA 2 and'driven from the shaft A I2 is connected to reciprocate thethread-guide I3 to cause it to traverse the yarn longitudinally of the winding spindle, these vconnections being shown in detail in Fig. 2 as common to machines of the present type. The traverse-frame II is adapted to pivot on the lshaft I2 to permit the thread-guide I to recede from the winding'` spindle 6 as the winding package increases in diameter, the movement of the traverse-frame being controlled by a dog I5 sliding in a grooved vquadrant I6 which lprevents retrogressive movey ment of the thread-guide, all as is common in machines of the present type.

` The traverse-frame II is counterbalanced by a depending, weighted arm I1 which swings toward vthe left as viewed in Fig. 1 as the threadguide II) moves` outwardly away from the winding spindle 6 during the course of the winding.

fastened to thence of the frame 2 of the winding machine is-a bracket38 ,formed with an outwardly and downwardly extending arm terminating in a horizontal shelf 39 which supports a `-slotted slub-catcher 40 of any suitable construction. VThe shelf 39 has a lateral extension in the form of a blade 4I -which is employed for a Apurpose as explained later.

Pivoted to the side The swinging movement of the arm I1 y-is employed in connection with the present invention to actuate the means which control the tension applied to the winding strand and also the regulation 'of the contact of the strand with a wetted member as explained more fully hereinafter.

The tension-device for applying resistance to the draft of the yarn as it feeds to the winding package may be of any suitable type and, as herein shown, it comprises a pair of concave-convex hubs mounted on the spindle 22 with the ends of' their arms bearing directly against the peripheral rims of the disks. The spindle 22 is mount-l ed to slide in a tubular sleeve24 screw-threaded through a bearing 25 on a bracket 26 fastened to the side of a horizontal trough 21 which, in the present form of construction, serves as the receptacle for the bath. of treating uid. The sleeve. 24 is adjustable in its bearing 25, being secured in place by a check-nut 28 with its righthand end, as viewed in Figs. 1 and 9, abutting the hub of one of the spider-springs 23. The opposite spider-spring 23 has its hub engaged by acollar 30 fastened to the end of the spindle 22 at 3l, this form yoiE construction providing `a collar 33 adjustably secured to the spindle and its opposite end bearing against a hub or enlargement 34 on the end of the sleeve 24 tends toA apply pressure to the springs 23 which act against the tension-disks 20. The left-hand end of the spindle 22 is preferably roundedA to adapt One arm 46 of the bell-crank lever 45 is connected by a link 48 to a member 49 carried by the depending arm I'I of the traverseframe II.

The. link 48 may be connected to the member 49 by means of a screw 56 engageable in any one of several holes. 5I to `adjust the position of the link relatively of the axis on which the traverseframe II swings to thereby regulate the extent of movement of the lever 45 during the winding of a package. The opposite arm 52 of the bellcrank lever 45 is pivotally connected to a link 53 jointed at its opposite end to the slide 36 on f which the cam 35 is mounted. The link 53 is preferably of two-part construction having its sections 54 and 55 telescopically connected, the upper section 54 terminating in a slotted portion 56 in which the end of the lower section 55 is slidably'A held. A slot in the end of the section 55 receives a screw 5l by whichit is secured to the section 54 to-provide for longitudinal adjustment betweenY the parts. Through this form of construction the link 53 is telescopically adjustable to vary its length whereof to vary the position of the slide 36 and thereby the relationship of the cam 35 to the end of the plungerpin 22. Referring to Fig. 9, the slide `36 is slidable in a guideway 58 formed as a part of the bracket 26, being held in place by a cover-plate 59 fastened to the front of the guideway.

The cam 35 is of novel construction comprising a plate-like member pivotally mounted on a stud 66 screwed into the slide 36. The lower portion cf the cam 35 is provided with an opening opening 6I toward the pivot-screw 60, this form of bifurcated construction ofl the cam providing that its two wings will be sprung apart slightly when the eccentric 62 is entered into the opening 6I, whereby to provide a frictional engagement to resist the turning movement of the screw 63. By

. turning the eccentric 62 the cam 35 may be swung on its pivot 60 to adjust, the angularity of its side edge which engages the end of the plunger 22 with respect to a vertical plane.

I t will be observed that during the movement of the transverse-frame II its depending arm Il will rock the bell-crank lever 45 to cause it to act through the link 53 to raise the slide 36, and

' Figs. 1 and 9 to relieve the pressure on the spider-springs 23 which act against the tensiondisks 20. A second lever 1| is pivoted on the screw l1 which forms the pivot for the bell' crank lever 45, this lever being adapted to be rocked during the swinging movement of thetraverse-frame by a wire link 12 connecting it to the depending arm |1 of the traverseframe. The lever 1| carries a weight 13 adjustable longitudinally thereof, this arrangement being in accordance with the usual construction whereof to provide for resisting the movement of the thread-guide I away from the windingV spindle B with the force of resistance gradually diminished as the package grows in diameter. It is pointed out, however, that thissecondary pressure lever 1| has no function in connection with the tension-controlling meanspreviously described.

It has been stated that it is of advantage to moisten or emulsify the yarn feeding to the winding package and it is necessary that this be accomplished subsequent to its passage through the tension-device. Consequently, the meistening device is interposed between the tension-device and the winding spindle and constructed to operate as explained hereinafter.` The trough 21, previously referred to, is mounted on brackets 15 attached to the legs 4 which support the machine bed 3, only one of t ese brackets being herein shown, see Figs. 1 an 2. The brackets 15 are adjustable vertically of the legs 4 `to regulate the height of the trough. The trough 21 is provided at each end with bearings 16 for a .horizontal shaft '11 which carries aseries of contact rolls or disks 80. The shaft 11 is mounted above the level of the liquid L in the trough 21, being rotatable in its bearings and driven from any suitable source of power by means of a grooved and stepped pulley 8| at one end, see Fig. l. A V-shaped belt Ic is adapted to engage in one or another of the grooves of the pulley 0| and thus the shaft may be rotated at the desired speed in accordance with the character of the winding being performed and the liquid material used for moistening the yarn.

The disk 80 may be of any suitable construc tion and as shown in Fig. 4 it comprises a hub l2 secured fast tothe shaft 11 bymeans of a screw 84. The hub 82 is reduced in diameter at one end and the disk 80 a relatively large bore forced onto the reduced portion of the hub to seat the disk against the shoulder formed thereby. It is to be particularly noted that the thickness of the disk is greater than the axial length of the reduced portion 85 of the hub 32 so that the forward face of the disk is located outwardly beyond the end of the hub to provide a central recess 05 surrounding the shaft 11; the purpesepf this construction being explained later. The rearward face of the disk 80 is beveled at its periphery to form an inclined face 01 and the forward face of the disk is preferably rounded at its periphery. A modified form of construction of the disk isillustrated .in Fig. 5 as being constructed of sheet-metal with an annular portion 83 fixed to the reduced portion of the hub l2 and a forward radial face 03 terminating in Y a cylindrical rim at its periphery with an inclined flange 00 at the rear. This form of disk may be spun or otherwise formed into shape from sheet-metal to reduce the weight and economize in the cost of manufacture.

Referring now to Figs. l and 2, the strand of yarny y feeds upwardly from its source of supply, arranged below, and passes through a suitable guide-eye 0| mounted on a member 02 attached to a downwardly-projecting larm of the bracket 25. Above the eye 0|- is a slub-catcher 03 of usual form through which the yarn drawn and thence it feeds between the tension-disks the end of the rod to hold'the 20 and passes upwardly through a second guideeye 0I attached to an ear on the bracket 20. From the guide-eye 94 the yarn is directed across the radial face of the disk 30 by being threaded through a movable guide-eye |00 which is displaced automatically during the progress of the winding to change the position of the yarn on the disk whereby to regulate its extent of contact therewith. 'I'he guide-eye |00 is fastened to a member or plate |0| supported by two parallel rods |02 and |03 which are slidably mounted in an angle-shaped arm |04 secured to the underside of the shelf 39 on the bracket 38.

The vupper rod |02 projects through a bushing |05 in the arm |04 and carries a-helical spring |06 held under tension between the end of the bushing and a pin |01 extending through the end of the rod. V'I'he spring |06 tends to slide the rods 02 and |03 in their bearings to move the guide-eye |00 toward the right as viewed in Fig. 2.0i the drawings to shift the strand y toward the axis of the disk whereof to increase its extent of contact with the face of the disk. This movement of ythe guide-eye |00 is controlled automatically during the building of each package on the winding spindle 3 by the movement of the thread-guide |0 away from the spindle. Conveniently, the shifting of the guide |00 is controlled'by a cam |10 carried at the end of an arm fastened to the depending arm I1 of the traverse-frame 'I'he 'cam ||0 is arranged to bear against the rounded end of the rod |02 and may have a straight face as shown in Fig. 6; or a cam |30 having a face of arcuate Icoritour may be employed in its stead, see Fig.

The cam ||0 has a hub ||2 pinned to the end of a rod H3 which projects through bores in a pair of spaced lugs or ears ||4 and ||5 projecting from the side of the arm A helical spring ||5 surrounding the end of rod I3 bears against the ear H4 and a collar ||1 screwed onto hub ||2 against the finished face of the ear |I5. The cam ||0` may be swung about the axis of the rod ||3 to adjust its inclination or eccentricity with respect to a vertical plane; a, screw ||9 passing through an arcuate slot |20 in an Vextension of the ear H5 being screwed into a boss |2| on the cam and tightened in place to secure the cam in its adjustedposition. The face of the cam |I0 which bears against the end of the rod |02 is of arcuate shape in side view, as shown in Fig.

1, with a curvature concentric to the axis on which the traverse-frame pivots, see 1. Consequently, as the thread-guide |0 is forced outwardly away from the winding spindle 6 during the growth of Iche winding package the swinging movement of the arm |1 of the traverse-frame will traverse the face ofthe cam across the end of the rod |02 to permit the spring |06 to slide the rod t0 the right as viewed in Figs. 2 and 3 to shift the guide-eye |00 in the same direction.

From the guide-eye |00 the strand of yarn y feeds upwardly through the slot in the slub-catoher 40, thence draws across a pin or guide-rod |25 and is directed therefrom to the thread-guide by passing it over a wire bail |26 at the top of the traverse-frame I The yarn y feeds through a groove in the thread-guide I0 to direct it onto the receiver which is rotatedby the spindle 6;

the present drawings illustrating. the yarn-rem ceiver in the formof a paper or'ber tube t of conical shape held on a mandrel |21 fast on the winding spindle 6.' Suitable starting and stopping means are provided in the winding vmachine and indicated in the present drawings, but

viewed in Fig. 1,6 thereby releasing the pressure of the collar 30A against the outer spider-spring 23 under the tension of` the spring 32. Stated briefly, the action of the cam 35 is torelieve the pressure of the springs 23 against the tension'- disks 20 whereof to vreduce the tension applied to the strand feeding to the package. In this manner the applied tension is progressively reduced from start to nish of the winding for a purpose as more fully explained hereinafter.

Meanwhile, as the traverse-frame is rocked I on its pivot the arm attached to its lower inserting it between the tension-disks 2 0.

Thence, the yarn is threaded through thexed guide-eye 94 and movable guide-eye |00, and

f then drawn upwardly through thevgroove in the slubg-catcher 40 and led across the wire bail |26. As the strand y is drawn upwardly from the guide 94 and through the guide v|00 it may contact with ,the periphery of the disk 80', but should this oc.

cur it will slide down over the rounded edge thereof to positionit against th-e face of the disk.

Likewise, `should the yarn lie across the rearward face of the disk 80 after being threaded through the guides, immediately it is placed4 under tension by starting the winding it will be drawn outwardly onto the beveled face 81 and then across the periphery of the disk and down onto its forward face. Thus,vthe present improved construction of the contact diskI insures that the strand will always be properly positioned for the wet treatment. The strand is placed in the groove of the thread-guide |0 and its end attached in any suitable manner to the receiver or' tube t. Before operatingthe machine the tension-device is adjusted to apply the proper degree of initial tension Ain accordance :with the character offlthe yarn and other variables. This adjustment may be accomplished by varying the length of the link 53 at the connection between itssections 54 and 55to raise or lower the cam 1325;' and further adjustmehtmay be secured by turning the eccentric 62 by means of the vscrew 63 to alter the vinclination of the contact edge of.

the cam 35. l

Upon starting the operation of the machine v the yarn is drawn from its supply through the various guiding' means mentioned above and wound onto the tube t as it is traversed longitudinally thereof by the thread-guide- |0 to dispose it in helical coils forming the layers which build up the package. At the start of winding the guideeye |00 assumes the position illustrated in Fig. 2 so that the strand of yarn y is drawn across the face of the disk 80 in a pathadjacent the outer periphery of the disk; this position of the guide |00 being regulated by adjusting the cam ||0 in the manner previously explained. As the winding progresses the swinging movement of the Vtraverse-frame causesits depending arm |1 to rock the bell-crank vlever 45 to `draw the link 53 upwardly and thereby raise the slide 36 carrying the cam 35. During this upward movement of the cam 35 its inclined face will act against the plunger 22 to force the latter to the right as weighted portion I1 is swung downwardly to draw the cam ||0 downward across'the end of the rod |02. -This traverse of the cam ||0 across the end of the rod |02 permits the latter to be moved to the right, asvvie'wed in Figa-2 and 3, by the action of its spring |06 to shift the thread-guide |06 in the same direction and thereby adjust the path ofthe strand y toward the axis of the disk 80. As the yarn is thus shifted in position on the face of the disk it will contact therewith to a progressively increasing extent as indicated diagrammatically in Fig. 8 of the drawings. Referring to this latter view ofA the drawings, at the start of winding a package with the yarn y feeding in a course as indicated at :c the disk 80 will have initially a wiping contact with the strand to an extent indicated by the arrow a'and then a second contact to an extent indicated by the arrow b. As the yarn is shifted to the right from the position indicated at n: to that indicated at z its contact with the disk Will be 1ncreased, and finally, at the completion of the winding, the strand will be directed in a course where it will have rst a wiping contact to the extent indicated by the arrow c and later a further contact indicated by the arrow d. In this way the contact of the yarn on the disk is increased progressively so that as its linear rate of travel increases suiiicient liquid will be applied thereto to insure a uniform saturation or coating of the yarn by the material in the bath L; it being understood that' as the disk 80 rotates in the direction indicated by the arrow f it will carry the liquid upwardly from the bath in a film covering the greater portion of its forward face. In some instances, for example, when the emulsion is of certain viscosity or diierent materials yare being wound it may be necessarytoshift the path of the strand inwardly of the disk with an accelerated rate of movement and this may be accomplished with an arcuately shaped cam |30 such as shown in Fig. '1. As the yarn passes beyond v the moistening device it draws through the slubj therefrom by the compression of the tensiondisks on the strand. The positioning of the slubcatchers 40' and 93 above and below the moistening trough 21 and the location of the tension-device 20 `below the trough serves to eliminate vibration of the yarn strand to provide for an accurate and .uniform wetting ofy the yarn. .Fur-

thermore, .due to the positioning of the tensiondevice 20 below the moistening trough none of the' emulsion will be deposited on the tensiondevice to clog its action, for example, cause the tension-disks to stick and prevent accurate connoted that the forward 80 is recessed circumferentially of the shaft 11 trol of the tension applied to the strand. Thus,

, by the present arrangement amore accurate control of the tension-device is attained. Moreover. it is importantin winding packages of moistened or emulsion-treated yarn that the tension on the strand be regulated so as not to become too great as the linear rate of draft is increased. That is to say, the tension of the yarn at the point where it is applied to the package must not be so great as to cause theouter layers of the package to constrict the inner layers to cause bulging at `the ends of the wound mass. Furthermore, unless the tension is maintained substantially constant or'gradually relieved throughout the winding of the full package there will be a tendency for the outer layers of winding to compress the inner layers and squeeze out the liquid solution'V which has been applied to the yarn. It will thus be seen that the present form of tension-device cooperates with the moistening or liquid-applying apparatus to insure uniform treatment of the whole length of yarn wound into the package.

The present invention also'provides further improvements in the construction and method of operation of the'moistening device. It has been face of the contact disk on which it is mounted. This provision is made so that if the yarn is lbroken at the package or between the package and the moistening device they end of the broken strand will not fall onto the drive-shaft 11 and be wound therearound to cause waste. Should the yarn u break above the the winding, contact means interposed between the tensioning means and the package for applying liquid to the yarn, and means to increase the extent of contact of the yarn with said contact means as the linear speed `of the yarn increases dui'ing the winding.

2. In a winding machine. the combination of means for rotating a package at a constant rate of speed, means for tensioning the yarn feeding to the package, means operative on the tensioning means for varying the tension on the yarn in accordance with its varying rate of linear speed,

between lthe tensioning means-and the package,

a contact member for engaging the feeding strand means to apply liquid to said contact member, and means to vary the extent of contact of the yarn with the contact member ln accordance with the varying speed of draft of the yarn.

3. Inv a winding machine, the combination of a winding spindle, means for traversing yarn longitudinally on the spindle to wind a package thereon, means for tensioning the yarn feeding guide-eye Iliilthe falling end will be deflected outwardly by the blade Il, previously referred to, so. that the end will fall across the face of the disk away from the shaft 11. Likewise, should the yarn break just below the guide |00 it will still fall across the face of the disk 8U laterally away from the shaft 'I1 and in either instance it will adhere to the wetted face of the disk due to molecular attraction and be prevented from sliding down onto the shaft 11 to be wound therearound. Usually, an annular bead of liquid is formed around the rim of the opening or recess 86 in the forward face of the disk 80 by the liquid collectingthereon and adhering thereto and this has the eifect to further guard against the broken end of the strand failing onto the-shaft 11. `Stated briefly, the annular recess 88 in the disk 80 tends to preventv the end of the yarn from being carried down onto the shaft 11 to be picked up thereby and wound therearound to cause a tangle or bunch resulting in waste.

As a further improvement contemplated by the present invention the cam $5 is adapted to be ad- Justed vertically to provide for its Proper initial action on the plunger rod 22 which regulates the pressure of the tension-disks 20; and in addition the angularity of the cam .can also be adjusted by rotating the eccentric 62 to varythe inclination of its contact face.

While the present apparatusis herein shown as embodied in a preferred form of construction, it is to be understood that various modiilcations may be made in the structure and arrangement of its parts withoutdeparting from the spirit or scope of the invention.
